Serotonin innervation in visual areas of cerebral cortex in macaque monkeys: Laminar distribution of tine and beaded axons. Distinct morphologic classes of serotonergic axons in primates exhibit differential vulnerability to the psychotropic drug 3,4-methylenedioxymethamphetamine. Before presenting the results of these studies, previous results in the 306 rodent will be briefly summarized, so as to put findings in the primate in proper perspective. Correlative anatomical studies indicate that these neurochemical changes are due to damage of serotonergic axons (O’Hearn et al. Serotonin-containing perikarya in the raphe nuclei of rats have a normal cytological appearance and show no obvious reduction in number (Molliver 1987; O’Hearn et al. This is noteworthy because guinea pigs (like humans) metabolize amphetamine primarily by side-chain deamination, whereas rats do so mainly by ring hydroxylation (Caldwell et al. In this regard, monkeys are of special interest because of their close phylogenetic relationship to humans and because they metabolize amphetamine in a manner similar to humans (Caldwell et al. This primate species was selected because of its size, availability, and prior use in neurotoxicity studies (Langston et al. This particular regimen of drug administration was employed because its prior extensive use in the rat (Commins et al. Two weeks after drug treatment, the animals were killed, the brains were removed, dissected, and then analyzed for their regional content of serotonin, doparnine, and noradrenaline using the method of Kilpatrick et al. These morphological studies showed that there was a marked reduction of serotonin-immunoreactive axons in the monkey forebrain (figure 1). Consequently, small increments in dose cause large increases in serotonin depletion in the monkey but not in the rat. However, there were clear cytopathologic changes in nerve cells of the dorsal (but not median) raphe nucleus. While the significance of these inclusions remains unclear, their staining characteristics suggested the presence of an increased amount of lipofuscin. More recent studies investigating the fate of these inclusion-bearing nerve cells have suggested that they do not die, and that their survival is associated with partial recovery of serotonin in the monkey forebrain (Ricaurte et al. It remains to be determined if recovery of serotonin is related to regeneration of serotonergic axons, and if the new axons innervate their original targets or form aberrant synaptic contacts. The animals were killed 2 weeks later, and regional brain serotonin concentrations were determined. As before, the multiple dose regimen produced a 312 large depletion of serotonin in all forebrain regions examined (table 5). By contrast, the single dose produced a depletion of serotonin only in the thalamus and hypothalamus.

Cross References Coma Perseveration Perseveration refers to pregnancy chinese calendar femara 2.5mg amex any continuation or recurrence of activity without appropriate stimulus (cf menopause 34 purchase 2.5mg femara overnight delivery. A number of varieties of perseveration have been described womens health garcinia cambogia scam buy femara 2.5mg visa, associated with lesions in different areas of the brain:. Cross References Aphasia; Dysexecutive syndrome; Frontal lobe syndromes; Intrusion; Logoclonia; Palinopsia Personification of Paralyzed Limbs Critchley drew attention to the tendency observed in some hemiplegic patients to give their paralyzed limbs a name or nickname and to invest them with a personality or identity of their own. This sometimes follows a period of anosognosia and may coexist with a degree of anosodiaphoria; it is much more commonly seen with left hemiplegia. A similar phenomenon may occur with amputated limbs, and it has been reported in a functional limb weakness. Cross References Anosodiaphoria; Anosognosia Pes Cavus Pes cavus is a high-arched foot due to equinus (plantar flexion) deformity of the first ray, with secondary changes in the other rays. Surgical treatment of pes cavus may be necessary, especially if there are secondary deformities causing pain, skin breakdown, or gait problems. Patients may volunteer that they experience such symptoms when carrying heavy items such as shopping bags which puts the hand in a similar posture. Hyperextension of the wrist (‘reverse Phalen’s manoeuvre’) may also reproduce symptoms. These are signs of compression of the median nerve at the wrist (carpal tunnel syndrome). Tinel’s sign), the sensitivity and specificity of Phalen’s sign for this diagnosis are variable (10–91% and 33–86%). The pathophysiology of Phalen’s sign is probably the lower threshold of injured nerves to mechanical stimuli, as for Tinel’s sign and Lhermitte’s sign. Cross References Erythropsia; ‘Monochromatopsia’; Phantom vision Phantom Limb Phantom limbs, or ghost limbs, are the subjective report of the awareness of a non-existing or deafferented body part in a mentally otherwise competent 276 Phonemic Disintegration P individual. The term was coined by Weir Mitchell in the nineteenth century, but parts other than limbs (either congenitally absent or following amputation) may be affected by phantom phenomena, such as lips, tongue, nose, eye, penis, breast and nipple, teeth, and viscera. Phantom phenomena are perceived as real by the patient, may be subject to a wide range of sensations (pressure, temperature, tickle, pain), and are perceived as an integral part of the self. Such ‘limbless perception’ is thought to reflect the mental representation of body parts generated within the brain (body schema), such that perception is carried out without somatic peripheral input. Reorganization of cortical connections following amputation may explain phantom phenomena such as representation of a hand on the chest or face, for which there is also evidence from functional brain imaging. Phantom Vision this name has been given to visual hallucinations following eye enucleation, by analogy with somaesthetic sensation experienced in a phantom limb after amputation. Similar phenomena may occur after acute visual loss and may overlap with phantom chromatopsia. Unformed or simple hallucinations are more common than formed or complex hallucinations. Phonagnosia is the equivalent in the auditory domain of prosopagnosia in the visual domain. Cross References Agnosia; Auditory agnosia; Prosopagnosia; Pure word deafness Phonemic Disintegration Phonemic disintegration refers to an impaired ability to organize phonemes, the smallest units in which spoken language may be sequentially described, resulting -277 P Phonetic Disintegration in substitutions, deletions, and misorderings of phonemes. Phonemic disintegration is relatively common in aphasic disorders, including Broca’s aphasia, conduction aphasia, and transcortical motor aphasia. The neural substrate may be primary motor cortex of the left inferior precentral gyrus and subjacent white matter, with sparing of Broca’s area. Clinical–anatomical correlation in a selective phonemic speech production impairment. Cross Reference Hyperacusis Phosphene Phosphenes are percepts in one modality induced by an inappropriate stimulus. The perception of flashes of light when the eyes are moved has been reported in optic neuritis, presumably reflecting the increased mechanosensitivity of the demyelinated optic nerve fibres; this is suggested to be the visual equivalent of Lhermitte’s sign. Eye gouging to produce phosphenes by mechanical stimulation of the retina is reported in Leber’s congenital amaurosis.

Introduction the misuse of mephedrone (4-methylmethcathinone) has been increasing greatly in Western countries over the last two years or so, especially in the club and dance scenes. Particular attention is paid to the settings in which these incidents took place, their symptomatology and physical characteristics; intervention/treatment opportunities; and toxicological and pathological findings. These results are related to the known pharmacological facts regarding mephedrone, its possible interactions with alcohol and other psychoactive drugs, and suggested clinical interventions and treatment(s). The relationship between mephedrone, other methcathinones, and other emerging novel psychoactive substances, as well as established stimulants is also examined. These developments are important as novel substances used for recreational use become more globally accessible through the use of the Internet. It has been readily available for purchase both online and in head shops as a ‘legal high’, and more recently as a ‘research chemical’; its circulation has been promoted by aggressive web-based marketing (Deluca et al. However, as we write, relatively few formal related papers and experimental/clinical data have been published (Dargan et al. However, the first Internet reference to it occurred reportedly in May 2003 (Power, 2009), but both its availability for purchase online (Camilleri et al. Since mephedrone appeared comparatively recently on the market, it does not feature in most drug use household surveys, and it is uncertain how many people present with a history of mephedrone misuse. Most available data originate from self-reported surveys and small focus group research. The main settings for mephedrone use appear to be nightclubs, parties and people’s homes (Newcombe, 2009). The 2011 sweep of the British Crime Survey, which covers households in England and Wales, found that 4. The majority of respondents who had taken mephedrone in the last year had also taken another drug. It is, therefore, likely that it is existing users of drugs that are taking mephedrone rather than new users drawn to drug taking. As a consequence, drug users may have switched to mephedrone, as it was seen as cheaper and more powerful than the currently available ‘traditional’ stimulants (Deluca et al.

These compounds include the cycloxygenase inhibitors breast cancer zipper hoodies purchase femara 2.5mg overnight delivery, aspirin [186-188], ibuprofen [189], diclofenac [190], xanthine derivative, pentoxifylline [191, 192], which is used for claudication in peripheral vascular disease, metal chelators, D-penicillamine [144] and desferoxamine [83, 144], thiamine pyrophosphate and pyridoxamine [193-195]. A number of deglycating enzymes have been discovered, especially in microorganisms, which remove the sugar bound to the protein molecule, and possibly provide these bacteria with energy substrates derived from glycated products [196]. These enzymes, known as amadoriases, include fructosylamine oxidases [197, 198], fructosamine-3-kinase [149, 150], fructoselysine-6-kinase [199], fructoselysine-3-epimerase (FrlC) [200], and glucoselysine-6694 Pharmacology phosphate deglycase [201]. The use of these enzymes or development of stable analogues for deglycation therapy remains speculative. More studies are needed for these compounds to establish their specificity and safety for therapeutic use. Alagebrium improved impaired cardiovascular function in older rhesus monkeys [207]. Alagebrium demonstrated promising results and a good safety profile in phase 2 clinical trials. In a clinical study involving 93 subjects, 50 yrs and older, with evidence of vessel stiffness (pulse pressure ≥60 mm Hg, systolic blood pressure ≥140 mm Hg, and large artery compliance ≤1. In another group of 13 patients aged 65±2 yrs with systolic hypertension (systolic blood pressure > 140 mmHg, diastolic blood pressure <90 mm Hg), alagebrium (210 mg/kg twice a day for 8 weeks) reduced vascular fibrosis and markers of inflammation [209]. Alagebrium (administered for 16 weeks) decreased left ventricular mass and improved left ventricular diastolic filling in another trial in 23 patients with diastolic heart failure [210, 211]. Thus, the authors could not verify the claims that alagebrium has beneficial effects in systolic heart failure [212]. Alagebrium has been reported to be a weak inhibitor of thiamine diphosphokinase and is unlikely to interfere with thiamine metabolism at therapeutic concentrations [213]. However, more in vivo studies are required before their therapeutic potential can be established.
